Abstract: A pulsating spray nozzle is particularly useful in an irrigation lavage for medical or veterinary use in delivering pulsating streams of liquid for cleansing wounds. The spray nozzle is designed to provide a steady operation over a wide range of flow rates. The nozzle comprises a hollow portable housing having an inlet connectable to a source of fluid. The nozzle housing has an end closure member providing an end wall having a plurality of fluid discharge orifices located symmetrically around the longitudinal axis of the housing. A rotary valve member is positioned in the housing for rotation along the surface of the end wall to control flow of liquid through the orifices therein. The rotary valve member comprises an arcuate valve plate supported on and integral with a plurality of radially extending vanes.

Abstract: A stream of water introduced to a shower head is split into two paths. The first water path is discharged in the form of a cone shaped spray. The second water path is channeled into a chamber containing a rotor rotationally responsive to the flow of water into the chamber and which rotor includes a chopper for regulating pulsed discharges of water through varying ones of a plurality of discharge ports. The proportional water flow in the two water paths is selectively variable. Air is introduced to the stream of water upstream of the water path split to aerate the water and reduce the quantity of water flow without an apparent water flow reduction to a user. A non-pulsating aerated shower head is also described.

Abstract: An adjustable massage shower head comprising, a housing defining a liquid input chamber for receiving a liquid, a flow guide mounted for axial movement in the housing defining a liquid flow passage from the input chamber and a turbine chamber, the flow guide having a spray bottom connected thereto with openings therethrough. A rotor valve is rotatably mounted and fixed at an axial position to the housing and disposed in the turbine chamber for rotation which produces a pulsating spray from the openings. A ring wall is disposed around the turbine chamber and has a plurality of ducts extending radially at an oblique angle therethrough for directing liquid against the rotor valve. The flow guide is axially movable to direct liquid against increasing areas of the rotor valve to increase the frequency of the pulsing spray.

The pinion carries a guide pin which is flushly engaged within the inclined slot for axial movement of the slide bushing when the pinion is rotated. At least one spray element is fixedly connected to the slide bushing for producing an adjustable output spray of liquid.

Abstract: A showerhead for controlling both water flow, spray direction and spray texture including a main housing for pivotally connecting same to a water supply line such that water flow is permitted through the showerhead in at least one pivoted position and terminated in at least one other pivoted position. A spray control carried by the showerhead permits varying spray texture and an elongate control rod having one end carried by the showerhead and a second free distal end for manual actuation by the user to pivot the showerhead about its connection to the water supply line to control water flow therethrough and actuate the spray control upon rotation of the control rod about its longitudinal axis.

Abstract: A showerhead which provides for a reduced flow volume through the showerhead includes a replaceable decorative cover. The showerhead has a skirt housing (24) which is swivelably mounted on a ball joint (10) connected to a water supply pipe. A generally cylindrical spray director (32) is welded to the skirt member (24) to provide a spray pattern emitting from the showerhead. An orifice plate (44) which reduces the flow volume and a face plate (50) which defines a spray pattern are disposed within the spray director (32) downstream of the ball joint (10). The face plate (50) is axially adjustable in order to vary the spray pattern as well as provide for a self-flushing showerhead. The decorative cover includes an annular shell (58) coaxially disposed about the spray director (32) and an end plate (64) which is snap-fit into the outlet of the spray director. In this way, decorative covers of different styles can be used with the same functional assemblies.

Abstract: There is disclosed a drip-forming device and system for drip irrigation. The device includes a tube and a rod having one end inserted into the tube by an adjustable amount, the rod being formed with at least one longitudinal groove which extends along at least part of the length of the rod and which is in communication with the part of the interior of the tube not occupied by the rod and whose depth decreases progressively away from the said one end over at least part of the length of the groove. With such devices, the output of each device can be simply adjusted to suit the local requirements, irrespective of the size, alignment and supply pressure of the complete irrigation apparatus, by adjustment of the depth of insertion of the rod in the tube. For a constant pressure the water output decreased with increasing depth of rod insertion -- i.e., as the minimum cross-section of the groove at the point of insertion of the rod in the tube decreases.

Abstract: The nozzle includes a sleeve and a hollow body concentrically disposed within the sleeve. A hollow cylindrical baffle housing is coaxially maintained within the body by vanes which extend between the housing outer wall and the body inner wall. Formed on the outer wall of the body is a thread which mates with a thread on the inner wall of the sleeve to permit rotation of the sleeve relative to the body between two stop positions. A baffle is secured to the baffle housing and is provided with a head which, as the sleeve is rotated toward the first stop position, approaches a baffle seat formed on the sleeve and thereby diminishes the quantity of liquid discharging from the nozzle.

Abstract: A pulsating shower head comprises a liquid chamber containing a spray block having an annular channel in which are disposed movable members in the form of rotatable balls and slidable segments driven by the force of the liquid to successively cover and uncover outlet openings formed in the annular channel to produce a pulsating effect on the liquid jets exiting from the spray block. The described shower head further includes additional outlet openings for producing non-pulsating liquid jets, and a manipulatable member for selectively connecting either the annular channel outlet openings to the liquid chamber in order to produce the pulsating liquid jets or to connect the additional outlet openings to the liquid chamber to produce non-pulsating liquid jets.BACKGROUND OF THE INVENTIONThe present invention relates to shower heads, and particularly to a pulsating type of shower head wherein a pulsating effect is produced on the liquid jets exiting from the head.A number of pulsating shower heads are known.

Abstract: The application discloses a valve and nozzle device for filling liquid into open-top cans or other receptacles one at a time, travelling on a conveyor.A commercial requirement is top speed achievable, and the conveyor moves the receptacles horizontally under a periodically discharging nozzle, which discharges a can-filling charge of liquid periodically, as rapidly as the can can be filled, and transported away to make room for the next charge. The apparatus disclosed discharges charges of liquid, under poppet valve control, through a discharge skirt formed to swirl each charge so that the charge impinges on the can, or can contents at a swirl angle, rather than straight down. By coordinating this swirl action with the downward velocity of the discharged charge, splash-out can be eliminated, and higher performance accomplished with a clean, non-splashing operation.

Abstract: The nozzle includes a sleeve and a hollow body concentrically disposed within the sleeve. A hollow cylindrical baffle housing is coaxially maintained within the body by vanes which extend between the housing outer wall and the body inner wall. Formed on the outer wall of the body is a thread which mates with a thread on the inner wall of the sleeve to permit rotation of the sleeve relative to the body between two stop positions. A baffle is secured to the baffle housing and is provided with a head which, as the sleeve is rotated toward the first stop position, approaches a baffle seat formed on the sleeve and thereby diminishes the quantity of liquid discharging from the nozzle.
